SAFETY-PIN.

.5PEOIFICA'JJION forming part of Letters Patent No. 334:.541, datedJanuary 19, 1886.

Application filed August 11, 1885. Serial No. 174.095.

To all whom it may concern.-

Be 'it known that I, HUBERT F. NEUss, of AiX-la-Chapelle, Germany, haveinvented an Improved Safety-Pin, of which the following is a full,clear, and exact description, refer- 8.108 being made to theaccompanying drawings, and for which I have obtained Letters Patent inGermany, No. 25,701, dated May 23, 1883.

Figure 1 shows a pin and its point-protecting collar, said collar beingremoved from said pin, and being partly in section" Fig. 2 shows a sideview of the pin and its collar, thelatter being removed from the pin.Fig. 3 is a sectional View of the collar placed on a pin. Fig. 4 is acrosssection on the line :0 as, Fig. 2.

This invention relates to improvements in safety-pins, in which thepoint of the pin is protected by being surrounded by a detachable collaror tube.

It consists in compressing one end ofa small metallic tube at one ormore points of its circumference, which compressions decrease the sizeof its bore, and thus allow the conical end of the pin to be wedgedbetween said compressions.

In the drawings, A represents the pin, the main part of which fits themonth end a of a thin metallic cylindrical tube or collar, B.

(No model.) Patented in Germany May 23, 1883, No. 25.701.

The other end of this tubethat is, the end to which the head D isattached-mas one or more compressions, E, or flat parts, as shown inFig. 4. These compressions destroy the round bore of the tube, making itat one end of the form shown in Fig. 4. The month end a of the tube B ismilled out flaring, so as to facilitate the insertion of the pin.

WVhen the conical or pointed end of the pin is to be protected, it isinserted into the tube B until it strikes the fiat face E, when by aslight turn of the pin it is firmly held by said compressions. The pinis removed by turning it in the opposite direction. The advantage ofthis method of forming the collar Bis, that aplain cylindrical tube canbe used for it by simply compressing one of its ends at one or moreplaces, which is a much more simple and inexpensive method of formingsaid collar than by reaming or otherwise.

I claim The combination of the collar B, which is compressed orfiattened'in one or more places, E, with the pin A, substantially asherein shown and described.
